I noticed that as of 2018-10-30 7:00 UTC, the API has started returning null when making a request to any endpoint. Looks like it might be a Cloudflare caching issue? This is currently breaking homebridge-sesame and I imagine other clients that use this API as well.

Thanks so much for reporting this issue! It should be fixed now, can you let us know if the issue persists? We really appreciate you bringing this issue to our attention and apologize for the the inconvenience caused! - CANDY HOUSE
